Palm vein technology is one of the upcoming methods of biometrics.. It is highly secure because it uses information contained within the body and is also highly accurate because the pattern of veins in the palm is complex and unique to each individual. Veins are internal in the body and it has a lot of differentiating features. So forgery is extremely difficult and thereby it produces a high level security .
It works by capturing a person’s vein pattern by radiating it with infrared rays. The sensor emits an infrared beam towards the palm of the hand. During this the blood flowing through the veins to the heart with reduced oxygen absorbs this radiation which causes the veins to appear as a black pattern. This pattern is recorded by the sensor and is stored in a database.During the time of identification it compares the vein pattern of the person to be identified with the pattern stored in databse. Vein patterns are unique to each individual, even identical twins have different patterns. And since they exist inside the body, they cannot be stolen thereby making this method of biometric tehnology more secure than others.

Applications:
Product development for financial solutions :
Financial damage caused by fraudulent withdrawals of money using fake bankcards has been rapidly increasing in recent years, and this has emerged as a significant social problem..
Vein authentication can provide two types of systems for financial solutions, depending on where the registered vein patterns are stored. In one method, the vein patterns are stored on the server of a client-server system. The advantage of this system is that it provides an integrated capability for managing vein patterns and comparison processing.

Login unit using PalmSecure:
The palm vein authentication login unit controls access to electronically stored
Information .As with the units for financial solutions, there are two types: a server type and an IC card type. Because the PalmSecure login unit can also be used for authentication using conventional IDs and passwords, existing operating systems and applications can continue to be used. It is also possible to build the unit into an existing application to enhance operability. In the early stage of introduction, the units were limited to businesses handling personal information that came under the “Act for the Protection of Personal Information” enforced in April 2005. However, use of the units is now expanding to leading-edge businesses that handle confidential information.

.Conclusion:
This paper explains palm vein authentication. The Fijitsu Palmsecure is a palm-vein based authentication system that utilizes the latest in Biometric Security Technology. Answering a worldwide need from governments to the private sector, this contactless device offers an easy-to-use, hygienic solution for verifying identity. This technology is highly secure because it uses information contained within the body and is also highly accurate because the pattern of veins in the palm is complex and unique to each individual. Moreover, its contactless feature gives it a hygienic advantage over other biometric authentication technologies. This paper also describes some examples of financial solutions and product applications for the general market that have been developed based on this technology.
